Pictomicrograph shows the posteromedial barrel subfield in layer IV of the rat somatosensory cortex. Barrels in the PMBSF are particularly large and distinct. The tissue in the image has been stained with cytochrome oxidase and is 50μm thick. The barrel field, like many regions of cortex, is organised into a topographic map. In the case of the ...
